INTRODUCTION. 

A  serious  problem  that  confronts  every  engineer  is  how  to 
make  most  available  that  mass  of  information  to  which  he  must 
constantly  refer.  Probably  of  all  the  engineers,  he  who  follows 
mining  has  the  most  widely  varying  problems  to  solve.  Each 
new  one  that  presents  itself  requires  thorough  study  and  the 
bringing  to*  bear  upon1  it  of  all  the  data  that  can  be  found.  If 
a  mining  engineer  is  called  upon  to  report  on  a  mine,  he  will  be 
aided  if  he  can  find  descriptions  written  by  some  previous  in- 
vestigator. Too  often,  however,  the  information  that  is  wanted 
is  just  the  information  that  cannot  be  found.  Public  and  private 
libraries  have  on  their  sh-elves  an  enormous  amount  of  material 
that  should  be  available  with  the  least  loss  of  time.  Many 
methods  of  indexing  have  been  used,  based  often  on  alphabetical 
order.  The  trouble  with  an  alphabetical  arrangement  is  that  it 
is  difficult  to  pick  from  the  titles  of  many  books  the  word  the 
initial  letter  of  \vhich  should  determine  its  place  in  the  alpha- 
betical list.  With  an  alphabetical  shelf  arrangement,  a  book  on

''Child  Study"  might  come  next  to  one  on  "Chilian  Mills,"  and 
one  on  "Grinding  Machines"  would  be  placed  considerably 
farther  along.  To  overcome  these  difficulties,  most  libraries  now 
use  what  is  known  as  the  "Decimal  Classification  and  Relative 
Index,"  called  the  "Dewey  Decimal  System."  As  its  name  indi- 
cates, this  system  is  a  numerical  one.  Each  subject  is  given  a 
number,  and  the  shelf  arrangement,  being  by  number,  brings 
similar  subjects  together.  All  knowledge  —  that  is,  we  might 
say,  all  reading  matter  —  is  divided  into  ten  classes,  as  follows  : 

0  General  Works. 

1  Philosophy. 

2  Religion. 

3  Sociology. 

4  Philology. 

5  Natural  Science. 

6  Useful  Arts. 

7  Fine  Arts. 

8  Literature. 

9  History. 

These  classes  are   divided   into    divisions.      Number  •  6,    or 
''Useful  Arts,"  is  subdivided  as  follows  : 

610.     Medicine. 

620.  Engineering. 
630.     Agriculture. 

640.  Domestic  Economy. 

650.  Communication  and  Commerce. 

660.  Chemical  Technology. 

670.  Manufactures. 

680.  Mechanic  Trades. 

690.  Building. 

These  divisions  are  again  subdivided  into  sections,  and  num- 
ber 620,  or  "Engineering,"  is  divided  as  follows  : 

621.  Mechanical  Engineering. 

622.  Mining  Engineering. 

623.  Military. 

624.  Bridge  and  Roof. 

625.  Road  and  Railroad. 

626.  Canal. 

627.  River  and  Harbor.. 


THE    COLORADO    SCHOOL    OF    MINES.  5 

:  628.     Sanitary.     Water  Works. 
629.     Other  Branches. 

"Mining  Engineering"  has  the  number  622,  and  books  or 
articles  numbered  622  would  be  placed  on  the  shelf  between  those 
numbered  621  and  those  numbered  623.  As  can  readily  be  seen, 
this  subdivision  can  be  carried  as  far  as  desired.  In  the  original 
classification  it  was  carried  to  five  figures,  as  is  given  on  page, 
ir,  and  for  a  general  library  this  is  sufficient.  For  the  library 
of  a  mining  man,  however,  it  is  not  enough.  For  example,  it 
will  be  noted  that  622.69  is  "Surface  Transportation."  The 
average  mining  engineer  will  accumulate  too  many  articles  that 
would  be  classed  under  "Surface  Transportation,"  but  yet  would 
be  different;  as,  for  instance,  "Aerial  Tramways"  and  "Wagon 
Roads."  Hence,  a  further  extension  or  subdivision  is  necessary, 
and  this  extension  has  been  carried  out  in  this  bulletin. 

The  principle  of  the  system  has  been  explained  in  order 
that  a  better  understanding  of  its  application  may  be  gained. 
Never  was  there  the  wealth  of  valuable  information  to  be  found 
in  technical  books  and  periodicals  as  at  the  present  time.  Every 
engineer  must  have  some  system  of  making  available  the  infor- 
mation that  he  may  want  at  any  time,  and  the  "Dewey  System" 
is  probably  the  only  scheme  that  has  stood  the  test.  At  the  Uni- 
versity of  Illinois  the  effectiveness  of  the  system  has  been  tried 
in  the  Engineering  College  and  has  been  found  thoroughly  satis- 
factory. If  engineers  will  take  the  small  amount  of  trouble 
necessary  to  become  familiar  with  the  system  they  will  find  it 
well  adopted  to  their  needs,  and  it  will  make  available  a  large 
amount  of  technical  literature  that  would  otherwise  be  lost. 

APPLICATION    OF  THE   SYSTEM. 

There  are  three  ways  in  which  the  classification  may  be  used 
by  engineers.  First,  by  a  card  index ;  second,  in  filing  articles 
and  clippings  without  an  index;  and,  third,  in  a  combination  of 
the  two  or  filing  away  the  material  according  to  the'  decimal 
system,  with  a  card  index  arranged  either  alphabetically  or  ac- 
cording to  the  "Dewey  System."  As  to  which  of  the  three  ways 
is  best,  opinions  differ;  also,  it  depends  on  the  extent  of  the 
material  to  be  indexed. 

CARD  INDEX. 

Many  engineers  use  a  card  index  arranged  alphabetically. 
If  they  notice  an  article  on  "Sinking  and  Timbering  Shafts,"  they 


6  THE     COLORADO     SCHOOL     OF    MINES. 

make  out  two  cards,  stating"  the  title,  length  and  perhaps  the 
character  of  the  article  and  where  it  may  be  found.  One  of  these 
cards  will  be  placed  in  the  drawer  under  "S"  for  "Shaft  Sinking," 
and  one  under  "T"  for  "Timbering."  The  only  difference,  if  the 
decimal  system  of  arrangement  is  employed,  is  that  the  cards, 
after  being  made  out,  would  be  given  proper  numbers  and,  placed 
in  the  drawer  in  their  numerical  order,  would  thus  avoid  the 
weakness  of  any  alphabetical  arrangement. 

The  card  index  finds  its  best  application  when  the  user  has 
in  his  office  only  a  few  of  the  articles  to  which  referenece  is 
made.  The  objections  to  it  are  two :  First,  there  is  usually 
trouble  in  finding-  the  magazine  in  which  the  article  occurs,  and, 
if  the  amount  of  material  is  large,  the  card  index  alone  would 
not  be  sufficient.  Second,  many  engineers  will  not  keep  up  a 
card  index.  This  is  without  doubt  the  most  serious  objection. 
Its  beneficial  use  and  general  adoption  by  large  business  con- 
cerns has  led  many  to  believe  that  the  card  index  alone  is  a 
"panacea  for  all  ills,"  but  they  should  remember  that  these  con- 
cerns have  competent  and  sufficient  clerical  help  to  keep  the  cards 
up  to  date,  an  advantage  which  many  engineers  do  not  enjoy. 

FILING    MATERIAL    WITHOUT    AN    INDEX. 

As  to  the  second  way  of  using  the  classification — that  is, 
for  filing  information  without  an  index — the  following  descrip- 
tion of  its  adoption  at  the  Colorado  School  of  Mines  will  prob- 
ably serve  best  to  enable  the  reader  to  judge  if  it  is  applicable 
to  his  requirements.  The  mining  department  has  a  case  con- 
taining a  large  number  of  pigeon  holes  5"  wide,  12"  high  and 
14"  deep,  which  are  numbered  according  to  the  Dewey  System, 
622.11,  622.12,  etc.  When  a  new  copy  of  the  "Engineering  and 
Mining  Journal"  arrives  it  is  read  and  then,  by  removing  the 
binding  clips,  the  different  articles  it  contains  are  taken  out  and 
placed  in  their  proper  pigeon  holes.  That  is,  if  there  be  an 
article  on  "Timbering,"  it  will  be  placed  in  number  622.2®  along 
with  articles  on  "Timbering"  that  may  be  taken  from  "Mines  and 
Minerals,"  "Mining  and  Scientific  Press,"  or  "Mining  Science." 
Then  when  any  information  is  desired  on  "Timbering,"  by  going 
to  that  pigeon  hole  we  have  all  the  latest  information  together. 
If  the1  number  of  articles  in  the  pigeon  hole  becomes  great,  they 
are  divided  into  their  proper  classes  and  placed  in  large  envelopes 
with  the  proper  number  on  the  outside.  That  is,  envelope'  num- 
bered 622.281  would  contain  all  the  articles  on  "Kinds  and 


THE     COLORADO     SCHOOL     OP    MINES.  7 

Properties  of  Timber  for  Mine  Use."  If  crowded  for  room, 
envelopes  could  be  used  entirely,  arranged  in  large  drawers  or 
otherwise.  Where  an  article  might  be  classed  under  two  head- 
ings, it  is  placed  where  it  has  the  most  weight,  and,  if  desired, 
a  reference  to  it  on  a  blank  sheet  in  the  other  pigeon  hole  can 
be  made.  Also  on  the.  blank  sheet  can  be  written  references  to 
articles  occurring  in  some  book  or  paper  which  may  be  found 
only  in  the  library.  As  most  strong  articles  occur  in  at  least 
two  of  the  mining  papers,  very  little  cross  referencing  has  been 
found  necessary.  The  article  taken  from  one  magazine  is  put 
in  one  place,  and  from  the  other  magazine  in  the  other  place. 
This  also  often  prevents  losing  one  article,  because  part  of  it  is 
on  the  same  sheet  with  another  article,  and,  of  course,  the  same 
results  would  be  secured  by  having  more  than  one  copy  of  the 
same  paper.  Two  advantages  of  the  method  are  worthy  of 
mention :  First,  the  articles  are  immediately  available,  and, 
second,  in  case  it  is  desired  to  take  the  information  on  a  trip,  it 
can  be  done  without  having  to  take  a  complete  bound  volume. 

BOTH    CARD  INDEX  AND  FILING. 

The  third  way  of  using  the  "Dewey  System"  is  really  a  com- 
bination. Books  and  magazines  are  placed  on  the  shelves  in 
their  proper  order  numerically  and  a  card  index  is  maintained 
referring  to  subjects  to  be  found  on  the  shelves  or  elsewhere. 
Where  there  are  many  books  and  the-  mass  of  material  is  large, 
this  is  to  be  recommended.  It  is  the  method  used  in  libraries 
where  only  the  card  index  is  alphabetical  for  the  use  of  the 
public. 

EXTENSION  OF  THE  CLASSIFICATION. 

In  extending  the  classification,  the  aim  has  been  towards 
as  logical  a  subdivision  as  possible.  The  original  classification, 
although  imperfect,  has  not  been  changed.  This  is  because  oi 
the  copyright  restrictions;  also,  because  of  the  reverence  for 
the  master  mind  that  evolved  the  entire  subdivision  of  all  knowl- 
edge. The  imperfections  can  be  seen  in  the  subdivision  of 
"Drainage,"  but  to  attempt  to  chan.ee  it  would  be  inadvisable,  be- 
cause so  many  have  already  adopted  it.  The  original  subdivision 
is  printed  separately,  so  that  it  may  be  torn  out  and  posted  near 
the  filing  case.  For  placing  many  articles  this  will  suffice  and 
will  save  many  references  to  the  extended  classification. 

In  order  to  cover  the  ground  of  mining  fully  it  was  neces- 
sary to  go  into  Geology  and  Mechanical  Engineering,  and  the 


8  THE     COLORADO     SCHOOL     OF    MINES. 

subjects  coming  under  those  divisions  that  are  found  in  the  min- 
ing engineer's  library)  have  been  put  in.  Those  on  Mechanical 
Engineering  were  taken  from  Bulletin  No.  9  of  the  University 
of  Illinois,  which  is  an  extension  of  that  subject.  Nothing  has 
been  put  in  on  Metallurgy  and  Assaying.  A  bulletin  covering 
the  extension  on  these  subjects  has  already  been  issued  by  the 
Colorado  School  of  Mines,  and  copies  may  be  obtained  from 
the  President  of  the  school. 

FORM  DISTINCTIONS. 

In  the  application  of  the  "Dewey  System"  it  has  been  found 
useful  to  employ  a  series  of  form  distinctions  or  divisions.  The 
literature  of  any  subject  may  often  be  advantageously  separated 
into  these  subdivisions,  which  are  as  follows : 

.001.  Statistics.  . 

.002.  Quantities  and  costs. 

.003.  Contracts  and  specifications. 

.004.  Designs  and  drawings.     Maps. 

.005.  Executive. 

.006.  Working  and  maintenance. 

.007.  Laws. 

.008.  Patents.     Machinery. 

.009.  Reports. 

.01.  Philosophy  or  theory. 

.02.  Compends.     Indices.     Directories. 

.03.  Cyclopedias.     Dictionaries. 

.04.  Essays.     Address.     Letters.     Theses. 

.05.  Periodicals.     Magazines. 

.06.  Societies. 

.07.  Education.     Study  and  teaching. 

.08.  Tables  and  calculations. 

.09.  History.     Progress  and  development. 

These  form  distinctions  may  be  used  not  only  to  subdivide 
general  subjects,  as  is  done  for  622  on  page  25,  but  they  can 
also  be  used  for  the  minor  subdivisions,  as,  for  example, 
622.141.09  would  be  the  history  of  mine  surveying  instruments. 

ALPHABETICAL    SUBDIVISION. 

The  use  of  an  alphabetical  arrangement  for  minute  sub- 
divisions may  sometimes  be  used  to  advantage,  as  has  been  done 
for  mines  and  mining  districts  on  page  33.  This  is  by  no 


THE     COLORADO     SCHOOL     OF    MINES.  g 

means  an  alteration  of  the  Dewey  System,  but  one  that  is  indi- 
cated in  his  book,  and  for  this  particular  case  is  the  only  logical 
arrangement. 

RELATIVE    INDEX. 

The  second  part  of  the  bulletin  consists  of  the  relative  in- 
dex, which  is  merely  a  finding  list  where  the  subjects  or  headings 
are  arranged  alphabetically  and  the  proper  number  is  given.  The 
placing  of  a  period  after  every  three  figures  in  a  number  is 
simply  for  convenience  in  reading.  The  first  three  figures  for 
mining  engineering  are  always  622,  and  may  be  replaced  by  a 
letter  or  sign  if  desired..
